Put the pizza bases on large oiled baking sheets – you may need 2 or 3. Spread 1 tbsp sauce or passata on each base, then scatter on the basil, tomatoes, mozzarella and Parmesan (or whatever you fancy). You can freeze the pizzas now, if you like, on the baking sheet, wrapped in cling film. Or if eating straight away, heat oven to 240C/220C fan/gas 9. Cook for 8-12 mins, until crisp and golden. To cook from frozen, remove the cling film and heat oven to 220C/200C fan/gas 7. Bake for 10-14 mins until crisp and golden.
